Oral environment control before restorative treatment
Maria Teresa Atta,Renata Loureiro Louto,Ian Matos Vieira
RGO : Revista Gaúcha de Odontologia , 2008,
Abstract: The aim of the present study was to describe caries disease treatment, by means of a clinical case report, with a view to promoting the patient’s health before definitive restorative treatments, considering that treatment should include changes in the patient’s dietary and hygiene habits, and not be restricted only to restoring lesions, as well as the establishment of an individualized treatment plan for each patient. Iodine-based antimicrobial solution was applied, instructions about oral hygiene and dietary habit changes were provided. The stepwise excavation technique was performed in tooth 15, mass excavation followed by the application of glass ionomer cement in the other teeth that presented carious lesions. White stain lesions were remineralized, and cicatrizes and fissures in the posterior teeth were sealed. After health was reestablished, the temporary restorations were replaced by definitive restorations. Changes in the treatment philosophy of caries disease, based on changes in the patient’s habits and removal of foci of infection have been presented with the object of producing an effective change in this paradigm, in order to increase the longevity of teeth with less operative intervention.

Revista de Enfermagem UFPE On Line , 2009,
Abstract: Objectives: to know the educational practices accomplished by the nurse from postpartum women on the breastfeeding and to discuss how they can contribute from early weaning reduction. Methodlogy: descriptive and exploratory study from qualitative approach. Six nurses of a maternity of a hospital unit in Niterói, Rio de Janeiro, Brazil, participated in this research. For data collection a roadmap for interview was used composed by two questions. Interviews has been recorded in MP3 and after were transcribed. Data collection was finished after the speeches saturation whose interpretation of them was done through Thematic Analysis. Results: two categories emerged: 1) lack of routines for orientation of the breast-feeding 2) Educational practices on the breastfeeding in spite of the difficulties. Conclusion: We noticed that the nurses stop accomplishing the educational practices regard to breastfeeding due to the great changing of the sector and absence support by the hospital direction.

Revista Saúde.Com , 2006,
Abstract: O Cimento de ion mero de vidro foi inventado no início da década de 70 do século passado, a partir do desenvolvimento do cimento de silicato. Desde ent o, passou a exercer um papel significante na odontologia restauradora. Primeiramente, era utilizado apenas como material restaurador em cavidades pequenas, posteriormente, passou a ser utilizado como material de cimenta o de pe as protéticas, como núcleo de preenchimento, material para base e forramento de cavidades dentárias e selamentos de fóssulas e fissuras. Mais recentemente passou a ser o material de escolha na técnica restauradora atraumática (ART), e também tem sido utilizado na medicina e fonoaudiologia em tratamentos em regi es ósseas. Sua popularidade evidenciou-se devido as suas propriedades biologicamente favoráveis, pois apesar de ainda possuir uma solubilidade inicial crítica e um comportamento estético insatisfatório, o cimento ionomérico libera flúor para o meio bucal, possui uma ades o química à estrutura dental e demonstra ser biocompatível. Com isso, ele evidencia propriedades anticariogênicas importantes, podendo assim ser utilizado em diversas situa es na odontologia.

Abstract: Objective: to identify the nursing academic's knowledge about the education in health. Methods: this is about a descriptive and exploratory study from qualitative approach that had as subjects ten nursing students from 3rd to 8th period of the nursing course of a private university in Niterói, Rio de Janeiro, Brazil. The choice was random and for the fact of the same ones have already lived the theoretical-practical teaching, where they had the opportunity to develop educational activities in health in the practical field. It was used as instrument for data collection an interview itinerary composed by open questions. The collection of data closed up after the saturation of the speeches and the interpretation of the same ones was accomplished through the Thematic Analysis. Results: after analysis of the data, two categories emerged: The nursing academics and the education in health; The approach of the education in health in the graduation. Conclusion: this study showed us that the education in health needs to be analyzed continually, discussed and understood in the graduation as an important practice in the nurse's assistance performance.
